Here are 10 other top traitors lurking in your cupboards or trying to tempt you in your local supermarkets such as Tesco and Sainsbury's when you do your weekly shop.

1. Avocado

Avocados are full of antioxidants and healthy fats but they come with a hefty energy content of between 250-400 calories each.

"Whilst there’s nothing wrong with having an avocado a day, it’s important to adjust your diet accordingly to account for the added calories," explains nutritionist Cassandra Barns.

2. Fruit yoghurt

The label might say ‘low-fat fruit yogurt’ and so you would think it would help with controlling your weight, but these yoghurts can contain up to EIGHT teaspoons of added refined sugar.

Often sugar is the next ingredient after milk in highest amounts in the yogurt.

"This type of yoghurt will be a high GI food causing your body to release more insulin to deal with the quick rise in blood sugar - and insulin is your fat storing hormone of the body," explains Dr Marilyn Glenville, nutritionist and author of Natural Solutions for Dementia and Alzheimer's.

3. Almonds

When it comes to nuts, almonds can be very moreish, and it’s easy to polish off a small 100g bag while racking up nearly 600 calories within minutes.

"Portion control is absolutely vital with a handful being the optimal portion size," says Cassandra Barns.

4. Tomato pasta sauce

You would think that tomato sauce would be healthy as it is low in fat but unless you make it yourself it can also be high in added sugar.

"And you if you then pour this over white pasta, which in itself is a high glycaemic index food because it is a refined carbohydrate like sugar then you have a double whammy on your weight gain," says Marilyn.

5. Dried fruit

Dried fruits are a highly concentrated source of sugar. For instance, fresh strawberries contain 6g of sugar per 100g, while dried strawberries contain 60g per 100g. This is more than double the amount of sugar found in ice cream.

"Excess sugar consumption is one of the top causes of weight gain. Sugar stimulates the release of the fat storage hormone insulin and triggers further food cravings, especially for sweet foods," says Cassandra.

To help curb sugar cravings try taking chromium which has a vital role in supporting normal blood glucose levels, and therefore helping to prevent the dips that cause us to crave sugary foods. Cassandra recommends Quest Vitamin’s Equigluco priced from £12.12 at www.qnutrapharma.com

Take one tablet a day, preferably with breakfast,suggests Cassandra.

6. Muesli

Muesli conjures up a picture of a healthy breakfast and is often accompanied in adverts in a beautiful alpine setting with trees, blue skies, clear lakes and clean air.

But not all muesli is the same and as with anything you buy you need to read the label and not just go by the hype on the front of the packet.

"Many can be laden with high amounts of added sugar and salt and this can turn a healthy breakfast into an unhealthy one," warns Marilyn.

7. Rice cakes

Rice cakes are often thought of as a low-fat, gluten-free health food. However, most rice cakes are made from white refined rice, leaving them with a glycaemic index close to 91 (pure glucose has a rating of 100).

8. Soup

You might think that a can of soup would be a light and satisfying meal but again you have to read the ingredients on the label.

"Many will have added sugar and some also have glucose syrup. Both the sugar and glucose is going to cause a rise in blood glucose and then an increase in release of insulin which triggers to store fat," explains Marilyn.

9.Cold-pressed juices

Cold-pressed is the new health craze with juice bars popping in London every few weeks. However does cold-pressed mean juices are actually healthier?

Cold-pressed is a special type of extraction method, where the juice is literally pressed out of the fruit or veg using very little heat. It is said that cold-pressed juice contains higher nutrition levels and a more intense flavour.

Cassandra says: "Whilst this is completely true, it doesn’t take away the fact that many of these juices are still packed full of the fruit sugar called fructose.

"Excess fructose consumption can lead blood sugar imbalances, obesity, metabolic syndrome and even increased risk of fatty liver disease. The best option would be to choose vegetable-only green juices which have very low sugar contents."

10. Skimmed milk

For years it seemed like common sense to choose the low-fat, low-calorie milk option. But by choosing skimmed milk, we are missing out on much needed fat-soluble nutrients like vitamins D, A and E.

"Fat really isn’t the health villain we have been led to believe," explains Cassandra

"It has now been disproved that full fat milk leads to weight gain and heart disease. In fact organic full fat milk provides us with many essential fatty acids like omega 3 and conjugated linoleic acid, which have powerful inflammatory and brain health benefits.

"Some people don’t produce the enzyme lactase, which helps them breaks down lactose, a sugar found in milk. You need this enzyme in your body in order to break down the lactose, otherwise it ferments in the gut causing pain, gas and bloating.

Cassandra urges people to try taking GI Natural from Nature’s Plus, priced at £23.75 from www.revital.co.uk, to promote digestive ease and comfort.
